Image Compression Method Based on QR-Wavelet Transformation
In this paper, a procedure is reported that discuss how linear algebra can be used in image compression. The basic idea is that each image can be represented as a matrix. We apply linear algebra (QR factorization and wavelet transformation algorithms) on this matrix and get a reduced matrix out such that the image corresponding to this reduced matrix requires much less storage space than th...
متن کاملCovert Communications through Hiding FM Waveforms in an Image
In this paper, we propose information encryption using two-dimensional (2-D) frequency modulated (FM) signals. The hidden information is embedded into a picture using the phase information of a 2-D FM prototype. The parameters of the 2-D FM prototype are optimized in order to achieve no or low bit error rate (BER) in detection. The cover image is partitioned into several blocks. In each block, ...
متن کاملAdaptive Wavelet Eye-Gaze Based Video Compression
We present a novel approach to compression of video frames based on the foveation behavior of the human visual system (HSV). Eye fixations on a video frame, as depicted by eye-gaze trace data, define an imaginary region of interest. The perceived resolution of the frame by the human eye depends totally on this eye-gaze (fixation) point. The resolution, then, decreases dramatically with the dist...
متن کاملDigital Audio Compression
Compared to most digital data types, with the exception of digital video, the data rates associated with uncompressed digital audio are substantial. Digital audio compression enables more efficient storage and transmission of audio data. The many forms of audio compression techniques offer a range of encoder and decoder complexity, compressed audio quality, and differing amounts of data compres...
متن کاملSeismic Retrofitting RC Structures with Precast Prestressed Concrete Braces- ABAQUS FEA Modeling
Precast prestreesed concrete braces are a new method for seismic strength of Concrete Structures which has the following benefits: a) no wet concrete work in construction site b) No bolt or anchorage to the existing frame c) easy to apply d) short construction period e) low construction cost, to evaluate seismic performance of strengthened structure a model consist of existing frame and concret...
